現有的電子產品中常見有金屬與塑膠共同製成的複合件，例如機殼，通常是金屬先成形後，再將已成形的金屬件與塑膠模製成形而形成複合件。In the existing electronic products, a composite member made of metal and plastic is commonly used, for example, a casing, usually after the metal is formed, and then the formed metal member and the plastic are molded into a composite member.
為了使金屬表面可以呈現不同的色彩而使物件的外觀較為美觀，通常可利用物理氣相沉積(PVD)製程在金屬表面鍍上金屬層，而選用不同材質的金屬可以呈現不同的金屬色澤。In order to make the metal surface can present different colors and make the appearance of the object more beautiful, the metal surface can usually be plated with a physical vapor deposition (PVD) process, and the metal of different materials can exhibit different metallic colors.
由於若要以物理氣相沉積製程在複合件的金屬表面鍍製金屬層時，也會使塑膠表面鍍到金屬層，如此不僅會影響塑膠表面的顏色，並會使塑膠本身的功能無法顯現，例如絕緣功能。If the metal layer is plated on the metal surface of the composite by the physical vapor deposition process, the plastic surface is also plated with a metal layer, which not only affects the color of the plastic surface, but also makes the function of the plastic itself incapable of appearing. For example, insulation function.
因此，要如何以物理氣相沉積製程在複合件的金屬表面鍍製金屬層且能保持塑膠表面不被鍍到金屬層，是需要解決的課題。Therefore, how to form a metal layer on the metal surface of the composite member by the physical vapor deposition process and keep the plastic surface not plated to the metal layer is a problem to be solved.

於是，本發明複合件的表面處理方法在一些實施態樣中，是適用於由金屬與塑膠共製的複合件的表面處理，該複合件具有露出的金屬表面及塑膠表面，該方法包含以下步驟：。 在該複合件的整體表面被覆保護漆以形成一保護層； 以電解方式去除該金屬表面的保護層，以使該金屬表面露出並於該塑膠表面保留該保護層； 在該塑膠表面被覆該保護層的狀態下，以物理氣相沉積製程在該金屬表面被覆一金屬層；及 將該複合件浸置於一脫漆劑中，以去除該塑膠表面的該保護層並同時去除在物理氣相沉積製程中沉積於該保護層上的金屬層。Therefore, in some embodiments, the surface treatment method of the composite member of the present invention is suitable for surface treatment of a composite member made of metal and plastic, the composite member having an exposed metal surface and a plastic surface, the method comprising the following steps :. Coating the protective lacquer on the entire surface of the composite member to form a protective layer; electrolytically removing the protective layer of the metal surface to expose the metal surface and retain the protective layer on the plastic surface; coating the plastic surface to protect the surface a metal layer is coated on the surface of the metal by a physical vapor deposition process; and the composite is immersed in a paint stripper to remove the protective layer on the surface of the plastic while removing the physical vapor phase A metal layer deposited on the protective layer during the deposition process.
於是，本發明複合件的表面處理方法在一些實施態樣中，該複合件具有相鄰的一金屬表面及一非金屬表面，該方法包含以下步驟： 在該複合件的至少該相鄰的金屬表面及非金屬表面被覆一保護層； 以電解方式去除該金屬表面的該保護層，以使該金屬表面露出並於該非金屬表面保留該保護層； 在該非金屬表面被覆該保護層的狀態下，在該金屬表面及非金屬表面被覆一金屬層；及 去除該非金屬表面的該保護層及該保護層上的該金屬層。Thus, in some embodiments, the composite member has an adjacent metal surface and a non-metallic surface, the method comprising the steps of: at least the adjacent metal of the composite member The surface and the non-metal surface are coated with a protective layer; the protective layer of the metal surface is electrolytically removed to expose the metal surface and retain the protective layer on the non-metal surface; and the non-metal surface is covered with the protective layer, Coating a metal layer on the metal surface and the non-metal surface; and removing the protective layer on the non-metal surface and the metal layer on the protective layer.
本發明至少具有以下功效：藉由電解去除金屬表面的保護層，可以確保金屬表面可完整露出且塑膠表面可由保護層完整保護，以使金屬表面形成金屬層後，能夠利用去除塑膠表面的保護層而去除塑膠表面的金屬層。如此能夠使複合件的金屬表面鍍製金屬層後，仍能使塑膠表面維持原貌以不失其原有的功能及外觀顏色。The invention has at least the following effects: by electrolytically removing the protective layer of the metal surface, the metal surface can be completely exposed and the plastic surface can be completely protected by the protective layer, so that after the metal surface is formed into a metal layer, the protective layer for removing the plastic surface can be utilized. The metal layer of the plastic surface is removed. In this way, after the metal surface of the composite member is plated with the metal layer, the plastic surface can still maintain the original appearance without losing its original function and appearance color.
參閱圖1與圖2，本發明複合件的表面處理方法之一實施例，適用於由金屬與塑膠共製的複合件的表面處理，複合件具有露出的金屬表面及塑膠表面，該方法包含以下步驟：Referring to FIG. 1 and FIG. 2, an embodiment of a surface treatment method for a composite member of the present invention is suitable for surface treatment of a composite member made of metal and plastic. The composite member has an exposed metal surface and a plastic surface, and the method includes the following step:
步驟S1，在該複合件的整體表面被覆保護漆以形成一保護層；Step S1, coating the entire surface of the composite member with a protective lacquer to form a protective layer;
步驟S2，以電解方式去除金屬表面的保護層，以使金屬表面露出並於塑膠表面保留保護層；Step S2, removing the protective layer of the metal surface by electrolysis to expose the metal surface and retain a protective layer on the plastic surface;
步驟S3，在塑膠表面被覆保護層的狀態下，以物理氣相沉積製程在金屬表面被覆一金屬層；及Step S3, coating a metal layer on the metal surface by a physical vapor deposition process in a state where the plastic surface is covered with a protective layer;
步驟S4，將複合件浸置於一脫漆劑中，以去除塑膠表面的保護層並同時去除在物理氣相沉積製程中沉積於保護層上的金屬層。In step S4, the composite member is immersed in a paint stripper to remove the protective layer on the plastic surface and simultaneously remove the metal layer deposited on the protective layer in the physical vapor deposition process.
配合參閱圖2，在本實施例中以包括金屬板1和塑膠塊2的複合件，且金屬板1和塑膠塊2各具有彼此相鄰的一金屬表面10及塑膠表面20為例說明實施步驟，且本例中複合件可為一電子裝置的機殼。Referring to FIG. 2, in the embodiment, a composite member including a metal plate 1 and a plastic block 2, and the metal plate 1 and the plastic block 2 each have a metal surface 10 and a plastic surface 20 adjacent to each other as an example to explain the implementation steps. And in this case, the composite member can be a casing of an electronic device.
在實施步驟S1之前，可以先將複合件清洗乾燥，以去除表面髒汙及雜質。Before the step S1 is performed, the composite member may be first washed and dried to remove surface dirt and impurities.
步驟S1，在複合件的整體表面以例如被覆保護漆方式形成一保護層3，亦即在金屬板1的表面10與塑膠塊2的表面20都覆蓋保護漆，而在金屬板1的表面10與塑膠塊2的表面20形成保護層3。可以利用噴塗的方式將保護漆噴塗在複合件的表面。保護漆可以例如矽樹脂漆、聚氨酯(PU)漆、環氧樹脂(EPOXY)漆、壓克力(Acrylic)漆、添加氮化硼二氧化鈦的耐高溫型漆、鐵氟龍漆等等。在複合件表面均勻噴塗保護漆約5至50微米，然後在攝氏100至180度的環境下烘乾固化，若使用紫外線固化型的漆料，可先在攝氏70度環境下乾燥後再使用紫外線光源固化。In step S1, a protective layer 3 is formed on the entire surface of the composite member by, for example, coating a protective lacquer, that is, the surface 10 of the metal plate 1 and the surface 20 of the plastic block 2 are covered with a protective lacquer, and on the surface 10 of the metal plate 1 A protective layer 3 is formed with the surface 20 of the plastic block 2. The protective paint can be sprayed onto the surface of the composite by spraying. The protective paint may be, for example, a enamel paint, a polyurethane (PU) paint, an epoxy resin (EPOXY) paint, an Acrylic paint, a high temperature resistant paint containing boron nitride titanium oxide, a Teflon paint, or the like. Spray the protective paint evenly on the surface of the composite part about 5 to 50 microns, then dry and cure in the environment of 100 to 180 degrees Celsius. If the UV-curable paint is used, it can be dried in the environment of 70 degrees Celsius before using ultraviolet rays. The light source is solidified.
步驟S2，以電解方式去除金屬表面10的保護層3，以使金屬表面10露出並於塑膠表面20保留保護層3。具體而言，步驟S2是將表面覆有保護層3的複合件置入電解槽(未圖示)，藉由金屬可導電的特性，使金屬板1作為電極，而將金屬板1表面10的保護層3電解而去除。同時，由於塑膠塊2不導電，而使塑膠塊2表面20的保護層3可以保留下來。在本實施例中，所使用的電解液含有的成分包括碳酸塩、氫氧化鈉、氫氧化鉀、表面活性劑等，其成分環保，不含有機溶劑例如醚、醇及芳香族類溶劑。藉由電解方式去除金屬表面10的保護層3，可以精確地區分金屬表面10與塑膠表面20，能夠確保金屬表面10的保護層3可以完全去除，且不會破壞塑膠表面20的保護層3，使得塑膠表面20能夠完整地被保護。In step S2, the protective layer 3 of the metal surface 10 is electrolytically removed to expose the metal surface 10 and retain the protective layer 3 on the plastic surface 20. Specifically, in step S2, the composite member coated with the protective layer 3 is placed in an electrolytic cell (not shown), and the metal plate 1 is used as an electrode and the surface 10 of the metal plate 1 is made of a metal conductive property. The protective layer 3 is electrolyzed and removed. At the same time, since the plastic block 2 is not electrically conductive, the protective layer 3 of the surface 20 of the plastic block 2 can be retained. In the present embodiment, the components used in the electrolytic solution include barium carbonate, sodium hydroxide, potassium hydroxide, a surfactant, and the like, and the components are environmentally friendly, and do not contain an organic solvent such as an ether, an alcohol, or an aromatic solvent. By removing the protective layer 3 of the metal surface 10 by electrolysis, the metal surface 10 and the plastic surface 20 can be accurately distinguished, and the protective layer 3 of the metal surface 10 can be completely removed without damaging the protective layer 3 of the plastic surface 20. The plastic surface 20 is allowed to be completely protected.
此外，在變化實施例中，亦可應用例如遮蔽膠、遮蔽帶、UV型乾膜或其他適當非金屬材料或產品或工法，在複合件表面形成保護層3，同樣可利用電解方式去除金屬表面10的保護層3。In addition, in a variant embodiment, a protective layer 3 may also be formed on the surface of the composite member by using, for example, a masking tape, a masking tape, a UV-type dry film or other suitable non-metallic material or product or method, and the metal surface may also be removed by electrolysis. 10 protective layer 3.
完成步驟S2後，可以再將複合件清洗乾燥，以去除複合件表面殘存的電解液及雜質。After the step S2 is completed, the composite member can be washed and dried to remove the residual electrolyte and impurities on the surface of the composite member.
步驟S3，在塑膠表面20被覆保護層3的狀態下，以物理氣相沉積(PVD)製程在金屬表面10被覆一金屬層4。具體而言，複合件經過電解製程後，已將金屬板1的表面10露出，而塑膠塊2的表面20仍覆蓋保護層3，通常在物理氣相沉積製程中，複合件的整體表面都會沉積金屬層4，也就是在金屬板1的表面10及覆蓋在塑膠塊2表面20的保護層3上都會沉積金屬層4。物理氣相沉積製程可以例如蒸鍍或濺鍍，由物理氣相沉積製程所形成的金屬層4可以與被鍍物(例如本實施例的金屬板1)表面的結合力較強，可以鍍的膜層種類較為廣泛，而能使形成的膜層的顏色種類較多也較漂亮，適用於提高被鍍物的外觀裝飾性能，且一般物理氣相沉積製程形成的膜層具有較佳的耐腐蝕性及耐磨性，使用壽命較長。In step S3, a metal layer 4 is coated on the metal surface 10 by a physical vapor deposition (PVD) process in a state where the plastic surface 20 is covered with the protective layer 3. Specifically, after the composite member is subjected to an electrolytic process, the surface 10 of the metal plate 1 is exposed, and the surface 20 of the plastic block 2 is still covered with the protective layer 3. Generally, in the physical vapor deposition process, the entire surface of the composite member is deposited. The metal layer 4, that is, on the surface 10 of the metal plate 1 and the protective layer 3 covering the surface 20 of the plastic block 2, deposits a metal layer 4. The physical vapor deposition process may be, for example, evaporation or sputtering, and the metal layer 4 formed by the physical vapor deposition process may have a strong bonding force with the surface of the object to be plated (for example, the metal plate 1 of the embodiment), and may be plated. The film layer is more widely used, and the formed film layer has more and more color types, and is suitable for improving the appearance decorative property of the object to be plated, and the film formed by the general physical vapor deposition process has better corrosion resistance. Sex and abrasion resistance, long service life.
步驟S4，將複合件浸置於一脫漆劑中，以去除塑膠表面20的保護層3並同時去除在物理氣相沉積製程中沉積於保護層3上的金屬層4。在本實施例中，脫漆劑採用市售的脫漆劑，選擇對應保護漆的脫漆劑即可，將複合件浸置於脫漆濟中約5至30分鐘，即可使塑膠塊2表面20的保護層3脫落，同時也使保護層3上的金屬層4連同保護層3一起脫離塑膠塊2表面20，如此即可使金屬板1表面10覆有金屬層4，而在塑膠塊2表面20不會覆蓋金屬層4以保持其原本的表面，從而不影響塑膠表面20的外觀及其功能。In step S4, the composite member is immersed in a paint stripper to remove the protective layer 3 of the plastic surface 20 and simultaneously remove the metal layer 4 deposited on the protective layer 3 in the physical vapor deposition process. In this embodiment, the paint stripper is a commercially available paint remover, and the paint remover corresponding to the protective paint may be selected, and the composite member is dipped in the paint strip for about 5 to 30 minutes to make the plastic block 2 The protective layer 3 of the surface 20 is detached, and at the same time, the metal layer 4 on the protective layer 3 is separated from the surface of the plastic block 2 together with the protective layer 3, so that the surface 10 of the metal plate 1 is covered with the metal layer 4, and in the plastic block. The surface 20 does not cover the metal layer 4 to maintain its original surface, thereby not affecting the appearance and function of the plastic surface 20.
在步驟S4之後，可以再將複合件清洗乾燥，以去除殘留表面的脫漆劑及雜質。After step S4, the composite member can be further cleaned and dried to remove the paint remover and impurities on the residual surface.
本實施例中，金屬板1材料可為例如銅合金、鎂合金、鈦合金或不銹鋼，但不以此為限。在變化的實施例中，複合件也可以是金屬與其他非金屬材料，例如玻璃，木材，陶瓷等不導電材質，一起製成。亦即本實施例的塑膠材料可以由其他非金屬材料替換。在變化的實施例中，被覆金屬層4的方法可以採用例如水電鍍。In this embodiment, the material of the metal plate 1 may be, for example, a copper alloy, a magnesium alloy, a titanium alloy or a stainless steel, but is not limited thereto. In a variant embodiment, the composite member may also be made of a metal and other non-metallic materials, such as non-conductive materials such as glass, wood, ceramics, and the like. That is, the plastic material of the embodiment can be replaced by other non-metal materials. In a variant embodiment, the method of coating the metal layer 4 may employ, for example, water plating.
綜上所述，藉由電解去除金屬表面10的保護層3，可以確保金屬表面10可完整露出且塑膠表面20可由保護層3完整保護，以使金屬表面10形成金屬層4後，能夠利用去除塑膠表面20的保護層3而去除塑膠表面20的金屬層4。如此能夠使複合件的金屬表面20鍍製金屬層4後，仍能使塑膠表面10維持原貌以不失其原有的功能及外觀顏色。In summary, by removing the protective layer 3 of the metal surface 10 by electrolysis, it can be ensured that the metal surface 10 can be completely exposed and the plastic surface 20 can be completely protected by the protective layer 3, so that the metal surface 10 can be removed after forming the metal layer 4. The protective layer 3 of the plastic surface 20 removes the metal layer 4 of the plastic surface 20. Thus, after the metal surface 20 of the composite member is plated with the metal layer 4, the plastic surface 10 can still maintain the original appearance without losing its original function and appearance color.
再者，本發明並揭露一種複合件的表面處理方法，包含以下步驟：提供一複合件，其具有相鄰的一金屬表面10及一非金屬表面20；於該複合件的相鄰的金屬表面10及非金屬表面20形成一非金屬層，例如前述保護層3；及以電解方式去除金屬表面10的該非金屬層，以使金屬表面10露出，並於非金屬表面20繼續保留該非金屬層。換言之，利用電解反應僅在金屬表面發生之特性，本發明可精確界定相鄰之金屬表面10及非金屬表面20間之界線，以僅將位於金屬表面10之非金屬層去除，且不致於影響破壞非金屬表面20之非金屬層。Furthermore, the present invention also discloses a surface treatment method for a composite member, comprising the steps of: providing a composite member having an adjacent metal surface 10 and a non-metal surface 20; adjacent metal surfaces of the composite member 10 and the non-metallic surface 20 form a non-metallic layer, such as the aforementioned protective layer 3; and the non-metallic layer of the metal surface 10 is electrolytically removed to expose the metal surface 10 and continue to retain the non-metallic layer on the non-metallic surface 20. In other words, by utilizing the characteristics of the electrolytic reaction occurring only on the metal surface, the present invention can precisely define the boundary between the adjacent metal surface 10 and the non-metal surface 20 to remove only the non-metal layer on the metal surface 10 without affecting The non-metallic layer of the non-metallic surface 20 is destroyed.
惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
